Explanation:

1. For levels of measurement:

• Ordinal data has ordered categories with no equal intervals between them.
• Interval data has ordered values with equal intervals, but no true zero.
• Ratio data has ordered values, equal intervals, and a true zero (where zero means absence of the quantity).
• Nominal data is unordered categorical data.

1. For variable types:

• Continuous variables can take any value within a range (including decimals/fractions).
• Discrete variables can only take specific, separate numerical values (counts).
